Custom Semen Collection

On-farm semen collection to suit your breeding schedule

Custom semen collection is a veterinary service designed to meet the specific reproductive goals of each producer. This highly controlled process involves the collection, evaluation, and processing of semen from elite sires using advanced reproductive technologies and strict biosecurity protocols. Evogene’s offers timed, on-farm semen collection to suit your breeding schedule—using elite young sires not yet available frozen or proven sires already in use. Any unused semen can be frozen for future use, adding flexibility and value to each collection. Convenient, efficient, and designed to deliver genetic gain where it counts.

Why Choose Custom Collection?

Minimise cryodamage, preserving sperm DNA
Improved fertilisation and embryo development rates

The highest-quality fractions are used for oocyte fertilization
Freezing of unused fractions
Tailored to individual bulls and breeding timelines
On-site flexibility while maintaining clinical-level standards
Veterinary oversight ensures animal welfare, hygiene, and sample integrity

Why is good semen so important?

In IVF, semen quality makes up half the equation — clean, high-quality, uncontaminated semen is essential for giving your donor the best chance at producing strong, viable embryos.

Can semen be collected on the same day as OPU?

Yes. Semen can be collected on the same day as an OPU program. Coordinating collection and egg retrieval ensures optimal timing for fertilisation and maximises the chance of producing viable embryos. This approach is particularly useful when using fresh semen for IVF.

What makes a good candidate for semen collection?

A good candidate is a healthy, well-developed bull with proven reproductive potential. Key factors include:

Overall health and body condition – the bull should be fit and free of illness.
Semen quality – good motility, morphology, and concentration are ideal.
Age and sexual maturity – bulls should have reached sufficient sexual development for reliable semen production.

Selecting the right candidate ensures high-quality semen, better IVF outcomes, and consistent breeding success.

How young can a bull be collected?

Semen collection can sometimes be performed on younger bulls, even before they are fully mature. While their semen may not yet be suitable for freezing, it can often be used successfully for fresh IVF, allowing breeders to utilise promising genetics early. The success depends on the individual bull’s age, development, breed and semen quality.
